Hi. As is known to medical fraternity, any would which is not healing for a such long time has to have a reason. Let us see ::: any foreign body underlying / such infection which needs special attention like fungal or so./ may be formation of a sinus tract/ cancer sometimes ... I would advise such a patient to visit a surgeon to see the reason and treat accordingly .... Wish you all the best for early and complete recovery. Please come back to us if you have any further queries and with reports and results .
